INFLUENCE OF SHIP NAVIGATION ON THE LONG TERM PREDICTION OF WAVE LOADS

The paper describes the statistical characteristics of a ship's navigation in real seas, based on weather reports by ships in operation. Distribution of mean value and variation of ship speed in some routes are discussed. Then an empirical model to describe navigational behaviour is presented by fitting simple formula. Several ship types are chosen as examples. Finally, a new method for the long term prediction is proposed to take in the effect of the ships handling in real seas. An example calculation is made for wave- induced midship bending moment and relative wave motion at the bow. Comparisons with results by conventional prediction method are made.
